AUXILIARY COMPONENT AND CONCRETE SLAB FOR PAVEMENT CONSTRUCTION AND METHOD OF PAVEMENT CONSTRUCTION

摘要

An auxiliary component for pavement construction comprises a cylinder (11), a base plate (12) and a leveling bolt (13). The cylinder (11) comprises a first cylinder part (11a) and a second cylinder part (11b) connecting and communicating with each other. The first cylinder part (11a) is provided with a hanger installing part and a slurry inlet. The bottom part of the second cylinder part (11b) is connected with the base plate (12). The base plate (12) is provided with a bolt extending hole (14) and a slurry discharging hole (15) which are communicated with the inner cavity of the second cylinder part (11b). The leveling bolt (13) comprises a bolt head (13a) and a screw (13b). The screw (13b) is arranged through the bolt extending hole (14). The bolt head (13a) is located in the second cylinder part (11b). The diameter of the bolt head (13a) is less than the inner diameter of the second cylinder part (11b). The invention also provides a concrete slab installed with the auxiliary component for pavement construction and a method of pavement construction. The auxiliary component for pavement construction improves leveling efficiency and durability by grouting the hollow area at the bottom of the base plate (12).
